SPECIFICATION forming part of Letters Patent N 0. 653,033, dated July 3,1900.

Application filed March 16, 1900. Serial No. 8,896. (No model.)

To ctZZ whom it may concern:

Be it known that 1, CHARLES H. MCINTIRE, a citizen of the United States,residing in Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in WVire Sleeves orConnectors; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

My present invention relates to improvements in connectors or joints forelectric conductors, and is especially applicable to joining insulatedwires or cables. Its object is to provide a simple, inexpensive, andeffective connector for electric conductors which can be readilyadjusted on and secured to the conductors to be jointed, and whichconnector besides strengthening'the joint will furnish a perfectelectrical contact.

- The invention consists in the improved connector and in thecombination and arrangement of the various elements thereof,substantially as will be hereinafter more fully described, and finallyembodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 is a front elevation, partly in section, of a joint made withmy improved connector; Fig. 2, a detail view of the connector detached;Fig. 3, a view similar to Fig. 2, showingaslight modification; Fig. 4, asectional view on the line ma: of Fig. 2, and Fig. 5 an enlargedcross-sectional view through the central portion of Fig. 2.

In said drawings, or represents a metallic tube circular incross-section and provided with a longitudinal slit f Figs. 2 and 5, andhaving its ends beveled, as at e e, and also provided in its centralportion with an elongated slot or opening f, either arranged inalinement with the slit f, as in Fig. 2, or diagonally, as at f, Fig. 3.

The wires 1) c to be jointed are first stripped of their insulationmaterial 19 and c to a length about equal to one-half the length of theconnector and are then inserted from opposite sides into the connectora. Solder is then poured into the slit and is allowed to flow around theconductors, whereby a good electrical contact is made between the parts,and besides the joint is sealed. WVhile the solder is being poured intothe slit and around the conductors the air contained in the connector isexpelled through the slot for f, and after said air is so expelledsolder is poured into said slot f or f, closing the latter and at thesame time uniting the end portions 12 and c of the conductors, and thusgreatly strengthening the joint. It must be remarked that the connectorCt is placed on the conductors in such a manner that the said endportions 11 and c of the wires 73 and 0 meet at about the centralportion of the connector and of its slotfor f, respectively. The bevelededges 6 6 enter the insulation material I) and c, as shown in Fig. 1,whereby the ends of the joint are closed substantially air and watertight. The joint is afterward completed by surrounding it withinsulation material d, as shown in dotted lines in Fig. 1.

Heretofore when straight-sleeve connectors were used the joints producedwere very seldom perfect and strong, as the air contained in theconnector and around the conductors was not sufficiently expelled, and,furthermore, no provisions were made to strengthen the joint bysoldering together or otherwise connecting the end portions of the wiresto be jointed. The above objections are completely overcome by mypresent invention, and it may be well to remark that under test a jointmade with myimproved connector i11- creases its conductivity from thirtyto sixty per cent. and its strength about one hundred per cent., and yetthe connector is very inexpensive and'is easily applied. I may alsoremark that the shape of the slotsfand f may be altered and that saidslots may be substituted by a square or circular hole so long as saidslots or holes are arrangedin that part of the connector where the endsof the wires to be jointed meet.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A sleeve or connector for electrical conductors, consisting of a tubeor sleeve substantially circular in cross-section and having its endportions beveled, and provided with a longitudinal slit extendingthrough the entire length of the sleeve or tube, and also provided withan enlarged opening or slot, substantially as and for the purposesdescribed.

2. A joint or connector for electrical conductors, consisting of a tubeor sleeve, substantially circular in cross-section and having its endportions beveled, and provided with a longitudinal slit extendingthrough its entire length, and also provided at or nearits centralportion with a slot or opening for the reception of soldering material,substantially as and for the purposes described.

3. A joint or connector for electrical con- CHARLES H. MOIN TIRE.
